So how did Navy get such an accurate time?  Using radio or satellites, right?

It's funny, we were the guys that the bridge got their time from, but
after the time tick, their chronometer was a superior timepiece.

Our Chelsea clocks kept time within 20 seconds or less a day, good enough for
radio logs.

In the Gulf of Mexico, you'd be able to set your clock to RCA's Port Arthur Radio who banged out his "CQ CQ CQ DE WPA WPA WPA TFC LIST QSW 418/HF =" to
beat any TTT CQ from NMG (USCG NOLA which served the entire Gulf.)
